Patent Strategy & Prosecution

  • The University of Pennsylvania as lead patent counsel in its alliance with Novartis to create the Novartis-Penn Center for Advanced Cellular Therapeutics, which focuses on the development of Chimeric Antigen Receptor (CAR) immunotherapy. This type of partnership between a university and big pharma is a landmark in the field of cell therapy in its breadth and magnitude. On August 30, 2017, the FDA approved, for the first time, the use of CAR gene therapy for treatment of acute lymphoblastic leukemia (ALL) in the United States. The approval of Kymriah ushers in a new approach for treating certain children and young adults with B-cell acute lymphoblastic leukemia.
  • A Connecticut university in obtaining allowance for a key U.S. patent. Prosecution of this patent required extensive negotiation with the USPTO Examiner, including the filing of multiple administrative petitions. The patent broadly claims proteolysis targeting chimera compounds.
  • A products manufacturer in drafting, filing and prosecuting patent applications related to its steel tubing product directed to both the new tubing and a new fitting, which are designed to allow the manufacturer to market a more cost-effective offering while maintaining its leading resistance to lightning and arc faults.
  • A Pennsylvania university hospital as its designated primary intellectual property counsel in its U.S. and foreign patent applications.
  • A leading Massachusetts hospital in a Federal Circuit decision vacating and remanding in-part a US Patent and Trademark Office (USPTO) Patent Trial and Appeal Board (PTAB) decision dismissing an interference suggested by the hospital directed to hair removal technology, especially for individuals with lightly pigmented hair. The Federal Circuit panel agreed that the PTAB’s denial of the hospital’s motion to add a claim to the interference was arbitrary and capricious.
  • A biotechnology company in a variety of matters, including patent preparation and patent prosecution.
  • A molecular diagnostics company in multiple national phase patent filings with related strategy discussions and prosecution.
  • A Pennsylvania university in a due diligence review that allowed for our client to sign an exclusive, worldwide licensing agreement with an oncology therapies company to develop and commercialize small molecule compounds that can be used to treat tumors, such as breast cancer.
  • A gaming company in filing and prosecuting its entire U.S. patent portfolio, including more than more than 200 U.S. patent applications. We also provide ongoing advice on strategic considerations related to the various U.S. patent applications in their portfolio.
